SAWING ATTACHMENT TO PLANI NG-MACHINES.

SPEGIFIGATION forming part of Letters Patent No. 288,147, dated November 6, 1883. Application filed July 10,1883. (No model.)

. ful Improvements in Sawing Attachments to -Planing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification- The object of my invention is to furnish an attachment to planing and flooring machines for trimming the edge or edges of all lumber being dressed to a uniform width, thus saving the expense of assorting and resawing before going to the flooring-machine. The attachment is driven by the same shaft that imparts motion to the planing or flooring.

machine, and the trimming is done either by saws or cutters which may be changed to any width while the machine is in motion. When attached, it makes one combined machine, and it consists in the novel construction and arrangement of its parts.

In the accompanying drawings, Figure 1 represents aside elevation of a planing-machine with my trimmer attached. Fig. 2 represents an end view of the same. Fig. 3 is an end view of creased journal-box J. Fig. 4 is a plan view of my yoke-brace. Fig. 5 is atop view of the bottom half of creased jourf nal-box J, with one end of shaft Klying in the same.

A represents the frame of the planer; B, the driving-pulley; O, the driven pulley, which drives the plane-shaft; c c 0 represent the upper rollers, while the dotted lines 0 0 0' represent the under rollers, and D represents the plant: or board passing through the machine. To this machine is secured my attachable and detachable trimmer E, in which standard F is fastened to the floor of the machine by bolts and nuts ff, and to the side of This seat is made to exactly fit the placed between the two front rollers. Standard H has on its upper end a sliding box, J, witha creased journal, to cause the shaft K to move with the box. The box has a lug, J, Fig. 3, at its bottom, so it maybe moved by the screw J Fig. 5 is a view of the lower half of the journal-box J, with the creased end of shaft K fitted into the same. As the journal-box is moved to the right or left, the shaft K is carried with it, as the other end .of said shaft is so journaled in standard F as to permit it to do so. Thus I am enabled to adjust the saw at to different widths of lumber without stopping the machine; but when I wish to move the saws or cutters any considerable distance along shaft K, I use the slot and feather. L.

Fig. 3 is an end section of the sliding box, showing the lug J.

The shaft K has one of its ends journaled in the upper end of standard F, and its other end journaled in the sliding box J, and has a slot and feather, L, its entire length, by means of which head and saw at can be secured'at any point necessary.

D shows the lumber passing through the machine and under the saw or cutter m.

It will be apparent that I can put as many cutters or saws on the shaft as needed for any purpose, and I may trim both edges of a board at one time, and at the same time rip it into several pieces.

B shows pulley driving cylinder of the planer, and W shows attached pulley for driving pulley O of my attachment.

- Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is-

In combination with the planer, my attachable and detachable trimmer E, consisting of 95 and feather L, head and saw m, pulley O,

driven by pulley W, and band G, all substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses. v
